Did the chicken come first, or did the egg come first?

From a scientific point of view, we start with the first life on Earth, and the first life on Earth should be infinitely close to the way bacteria or viruses reproduce.

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

Did the chicken come first, or did the egg come first? This classic question has plagued mankind for hundreds of years. Recently, British scientists claimed to have solved the mystery, and the answer is that there are chickens and then eggs, on the grounds that they have found a protein that can catalyze the formation of eggshells only found in the ovaries of chickens.

According to the British "Daily Mail" 14**, researchers from the University of Sheffield and the University of Warwick recently wrote an article entitled "Structural Control of Eggshell Protein Crystal Nucleus", which elaborated on the conclusion that scientists used a supercomputer to "amplify" the egg formation process: a protein called Ovocledidin-17 (referred to as OC-17) is a catalyst that accelerates the growth of eggshells, without OC-17 proteins, the appearance of eggs cannot crystallize to form eggshells. This protein converts calcium carbonate into the calcite crystals that make up the eggshell.

Calcite crystals are found inside many bones and eggshells, but hens form calcite crystals faster than any species——— producing 6 grams of eggshells every 24 hours.

Colin Freeman, Ph.D. from the Department of Engineering Materials at the University of Sheffield, said: "Scientists have previously discovered the OC-17 protein and speculated that it is involved in egg formation. But after careful research, we finally understood how it controls the egg formation process.

Interestingly, various birds appear to have proteins like OC-17 that catalyze eggshell formation. Freeman concluded, "There is a place to live with the eggshell, yolk and liquid that protects the chicks, and there would be no eggs without the OC-17 protein in the ovaries."

Therefore, there must be chickens and then eggs. ”

Hope it helps you, thank you.

Chicken or egg? Aristotle, a scholarly authority active in 3000 B.C., said: "There is an egg without a father and a mother, and the first chicken pops out of the egg".

The chicken that came first, God created the animal, according to science, there was also a chicken, there was a man or a woman, the answer is that there was a man and then a woman, and a woman was a man's flesh and bones.

Did the chicken come first or the egg came first? It's a difficult question for us. But on the issue of first-come-first-served or first-served, we can make a decision.

It doesn't matter! It's going to eat in your stomach anyway, why are you tangled in this?

It's a philosophical question, depending on how you look at it.

Chicken or egg?

Do you think it came first, the chicken or the egg?

Here's the answer: did the egg come first, or did the chicken come first? Why can't adults tell clearly?

Aren't ducklings cold? The shore is starting to freeze, but you are happily bathing in the river? And the butterfly clothes, who made them? Why is it always so beautiful and trendy (mao)?

The topic requires imitation, there are not many words learned in the second grade, so you can write simple, chicks are usually visible, chicks hatched from eggs, chickens or eggs first, people have not been clear, you can use this as an example. Who did it exactly? Referring to this sentence, is it written that the egg came first, or the chicken came first?

Why is it always so beautiful and trendy (mao)? Why can't adults tell me what is written in this sentence? The answer is written.

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

Do you think it came first, the chicken or the egg?

From a scientific point of view, we start with the first life on Earth, and the first life on Earth should be infinitely close to the way bacteria or viruses reproduce.

There were eggs first, because before the first hens clucked after laying eggs, there were dinosaur eggs in the world!

Eggs, eggs, of course, are the first chickens to have eggs,

The first chicken, many texts say that the mother hen is called, and there is no one called the egg mother.

The answer is chicken first, then egg.

The egg or the chicken came first in the world? In order to find the truth, the chicken clan actually traveled to 100 worlds, where there were eggs or chickens first? In order to find the truth, the chicken clan actually crossed over to 100

From a scientific point of view, we start with the first life on Earth, and the first life on Earth should be infinitely close to the way bacteria or viruses reproduce.

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

There are chickens and then eggs, eggs are a cell of chickens, there are many chickens that do not lay eggs in this world, and there are countless eggs that have not become chickens, which shows that eggs are just a part of the chicken, and this part must be mated This physical and chemical reaction can be produced, just like there is no aluminum alloy in the world, eggs are also synthetic, so there are chickens and then eggs.

First there are chickens and then there are eggs, because they are eggs.

There are eggs first, then chickens, because there are eggs to hatch chickens.

Do you think it came first, the chicken or the egg?

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

The egg or the chicken came first in the world? In order to find the truth, the chicken people actually traveled to 10 billion years ago!

First there are chickens, then there are eggs.

July 14th.

According to the UK**, the puzzle of the century that plagues mankind, "chicken and egg or egg", has finally been answered. British scientists say: first there is a chicken and then there is an egg.

Scientists explain that eggs can only be formed under the catalysis of a chemical that is only found in the ovaries of chickens.

The chemical was found to be a protein called OC-17, which acts as a catalyst and accelerates the formation of eggshells. And the eggshell is like the home of the egg yolk, protecting the egg yolk and eventually turning into a chick.

Scientists have been zooming in on the formation process of eggs through computer technology, and have found that OC-17 plays a crucial role in the early stages of egg formation. In response to the OC-17 protein, calcium carbonate is converted into calcite that forms eggshells.

Scientists believe that the discovery, in addition to understanding how chickens produce eggs, could also lead to the development of new materials or procedures.

Chicken lays eggs: process:

There is a protein called OC-17 in the ovaries of chickens - (catalytic action) - calcium carbonate is converted into calcite that makes up the eggshell - the eggshell is like the home of the egg yolk - the yolk breaks out of the shell and becomes a chick.

Do you think it came first, the chicken or the egg?

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

It's very simple, first there are bacteria, then all the bacteria come together to form a living organism, and then slowly become a deformed creature, and then after billions of years of evolution into the current chicken, and then the chicken lays eggs on its own. In the end, it's the bacteria that come first.

According to the latest reports::: There are chickens and then eggs in the world. Scientists have found OC-17 in eggshells, a protein element that can only be produced in the ovaries of fertile hens.

First there are chickens and then there are eggs because of the eggs, are the eggs in front of the eggs.

British scientists have confirmed that it is the chicken that comes before the egg

There were chickens first, because chickens were born from wedlock.

In terms of biology, it should be the chicken first and then the guts.

You tell me whether there came first with men or with women.

Our history teacher said, "Okay! This is a serious issue, so we won't discuss it! ”

It's a bit esoteric

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

Chicken or egg? Aristotle, a scholarly authority active in 3000 B.C., said: "There is an egg without a father and a mother, and the first chicken pops out of the egg".

First there are chickens, because chickens - eggs, chickens are in front, hehe

The boil is laid by the chicken, and the primitive chicken is not necessarily hatched from the egg.

Chicken or egg?

Do you think it came first, the chicken or the egg?

Do you think it came first, the chicken or the egg?

This question has been around for a long time, but there is no one absolutely right answer, and there can be no one.

This is not a matter of science, but of logic.

Let's assume that the chicken here refers specifically to the domestic chicken, and the egg refers specifically to the egg. Otherwise, if the dinosaur egg is also counted in the scope of "eggs", the answer must be that there are eggs first, and there will be no debate for so long.

The answer can be either the chicken or the egg. It depends on the identification of the first "chicken" and the first "egg".

According to the more popular view now, birds (including chickens, of course) evolved from a branch of the dinosaurs. And the evolution of species is an extremely long and gradual process. Even from the end of the Cretaceous period, when the dinosaurs became extinct, it is more than 65 million years ago, and the evolutionary process from dinosaurs to birds must have begun even earlier.

In such a long evolutionary process, it has gone through millions of generations and countless small evolutions to come to the "chicken" we see today and discuss here.

Suppose the first dinosaur that started this evolutionary process was N1, and it laid an egg N1, N1 hatched the second generation of N2 in the evolutionary process, and N2 gave birth to the egg N2, followed by N3, N3, N4, N4, N5, N5, 、......ni、ni、ni+1、ni+1……Until today's N1000000 and N1000000, in this process, the characteristics of dinosaurs continue to decrease and the characteristics of chickens continue to increase, so the generation of animals Ni is defined as the first "chicken", and which egg Ni is defined as the first "egg", which is the crux of the problem. Suppose N800000 is defined as the first "chicken" and its egg N800000 is defined as the first "egg", and the conclusion is that there is a chicken and then an egg, and if N799999 is defined as the first "egg" and its hatched N800000 is defined as the first "chicken", the conclusion becomes the first egg. The process is so long, the evolution is so slow, the changes in each generation are so small, there is absolutely no clear demarcation, before there was no doubt about the dinosaur, and one generation has changed into the undoubted chicken.

In this process, you can define N8000000 as the first chicken, N7000000 as the first chicken, and the same is true for the definition of eggs.

So don't seek a clear and absolutely correct answer to the question of chicken or egg: it can be the chicken or the egg, depending on your identification of the first "chicken" and the first "egg".

From a scientific point of view, we start with the first life on Earth, and the first life on Earth should be infinitely close to the way bacteria or viruses reproduce.

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

The egg hurts, even if the chicken gives birth to the chicken, do you still have to ask, first the chick or the hen, it is very boring to abstract two concepts from a complex process and make a logical question.

There was a chicken first, Darwin said, "The Origin of Species", p. 286, Yilin Publishing House, 1988 edition.

There are eggs first, not necessarily eggs.

There was a fade in the days of the dinosaurs, but there were no chickens at that time.

It's a boring question. Complete.

It depends on history, and I don't know! But I guess it's the chicken before the egg!!

First there are chickens, then there are eggs. Ancestors first domesticated chickens as an animal before laying eggs.

Chicken or egg? It is a philosophical and scientific mystery that has been difficult to solve for the ages. According to the British "Daily Mail" on July 14**, British scientists have found that the formation of eggshells depends on a protein that can only be found in the ovaries of chickens.

Therefore, there must be chickens before eggs can exist.

This protein, known as ovocledidin-17 (or OC-17), acts as a catalyst to accelerate the formation of eggshells, which are essential for protecting the yolk and whites as chicks develop.

Scientists at the University of Sheffield and the University of Warwick in the United Kingdom used the supercomputer HECTOR to zoom in on the structure of an egg, and the results showed that OC-17 played an important role in initiating crystallization, the early stage of eggshell formation. The OC-17 protein converts calcium carbonate into the calcite crystals that make up the eggshell. Calcite crystals can be found in large numbers of bones and shells, but chickens form these crystals faster than other species, producing 6 grams of eggshells every 24 hours.

In the past, the answer to the question of chicken or egg has largely relied on evolutionary perspectives. Some scholars believe that the eggs hatched by the cross-breeding of two chicken-like species to become the first chicken in history, so the egg preceded the chicken. Colin Freeman, from the Department of Engineering Materials at the University of Sheffield, says scientific evidence now suggests that chickens actually appear before eggs.

OC-17 has previously been linked to eggshell formation, and new research has further explained the process by which it controls eggshell formation. Interestingly, scientists have found that different birds seem to have different proteins but do the same thing.

Professor John Harding, also from the department, said the discovery had other uses. Understanding how chickens form eggshells is fascinating in itself, but it also provides clues to the design of new materials and processes. In the field of materials science and technology, nature offers innovative solutions to almost any problem, and scientists can also take inspiration from the process of eggshell formation in chickens.
